Abstract
The case of a woman on day four post partum with sensorimotor deficit of the right side and CT evidence of a left temporofrontal hemorrhagic lesion, is presented. Attending physicians requested cerebral angiography. To better evaluate the clinical justification of requested imaging procedure the patient medical history and performed CT examination were carefully revised. According to this analysis and based on a clinicoradiological methodology, the request of a cerebral angiography was considered appropriate. The examination showed several radiological signs but a definitive diagnosis could not be established. Second choice imaging procedures were analyzed and MRI completed with MR-angiography was performed. It allowed to document transverse and sigmoid sinus thrombosis. Therefore, in the diagnosis of venous sinus thrombosis, MRI combined with MR-angiography was shown to be a method of first choice while angiography plays a major role in therapy for intravascular thrombolysis.

Abstract
Acute mastoiditis is a serious complication of acute otitis media in children. Suppurative disease in the mastoid region occasionally spreads to the adjacent dura mater of the posterior and middle cranial fossae and the sigmoid sinus by means of thrombophlebitis, osseous erosion, or anatomic pathways, producing intracranial complications. Computed tomography (CT) should be performed early in the course of the disease to classify the mastoiditis as incipient or coalescent and to detect intracranial complications. On the basis of the clinical features and imaging findings, the disease is managed conservatively with intravenously administered antibiotics or treated with mastoidectomy and drainage plus antibiotic therapy. CT is therefore a decisive diagnostic tool in determining the type of therapy. In addition, magnetic resonance imaging is performed in patients with clinical symptoms or CT findings suggestive of intracranial complications because of its higher sensitivity for detection of extraaxial fluid collections and associated vascular problems.

Abstract
Dural sinus thrombosis has protean clinical and radiological manifestations ranging from minimal effacement of sulci with no symptoms to severe haemorrhagic infarcts associated with focal deficits, coma and even death. An uncommon form of presentation is characterized by unilateral lobar haemorrhage associated with extensive oedema and parenchymal distortion. In an acute presentation, this might resemble haemorrhage into a tumour. In delayed presentations, the haematoma, being iso- or hypodense and showing peripheral ring-like enhancement, can mimic aggressive tumours or infective processes. As this is an uncommon condition, misdiagnosis is common with the potential for mismanagement and adverse outcomes. We present five such consecutive cases that were initially misdiagnosed as other entities. Each of these cases on closer inspection show features observed on CT and MRI that should have suggested a diagnosis of dural venous sinus thrombosis. One of these cases progressed to not only extensively involve the superficial sinuses but also the deep veins, with a significant adverse outcome. The imaging features of this interesting variant of dural sinus thrombosis are reviewed. The haemodynamic basis for haemorrhage and anatomical basis for the lateralization of the lesions are discussed.

Abstract
This was a retrospective study to determine different etiologies of cerebral venous thrombosis (CVT) in childhood and to correlate extent and location of thrombosis with the etiology and the age of the child as well as the final outcome. In addition, the radiologic approach is discussed. This was a retrospective analysis of 19 children with CVT. The children were examined by contrast-enhanced dynamic CT. Radiologic findings were correlated with the etiology of CVT. Cerebral venous thrombosis is not as infrequent in children as has been thought. Cerebral venous thrombosis in children can occur due to trauma (n=9), infections (n=7), or coagulation disorders (n=3). Extent and location of thrombosis, as well as complications, final outcome, and therapy, depend on the etiology. Computed tomography remains a valuable primary imaging modality in the diagnosis of CVT in the acutely injured or diseased child.

Abstract
BACKGROUND Cerebral venous sinus thrombosis (CVT) is a potentially serious but treatable disorder that has been underdiagnosed in the past. Delay in diagnosis and treatment of this disorder has resulted in the death of one of our patients. AIM To review the local experience with CVT in order to identify factors that may allow diagnosis and appropriate treatment decisions to be made more readily in the future. METHODS A retrospective review of all cases of CVT diagnosed or treated at Auckland Hospital between 1990 and 1999. RESULTS Twenty-five cases of CVT were identified. The number of cases diagnosed increased from less than one per year in 1990-94 to eight in 1999. Clinical signs at presentation included headache (96%), focal neurological deficits (60%), seizures (40%) and papilloedema (43%). Delayed diagnosis after admission to hospital occurred in two young women presenting with neurological symptoms during pregnancy or puerperium, in two cases in whom focal symptoms were not explained by negative computed tomography and in five cases presenting with intracerebral haemorrhage. Twenty patients received anticoagulant therapy and their condition remained stable or improved after treatment. CONCLUSIONS The diagnosis of CVT should be considered in women with any neurological symptoms during pregnancy or puerperium and in all cases of unexplained intracerebral haemorrhage. CVT should also be considered in cases of recent onset and progressive headache, particularly when associated with focal neurological symptoms or signs, seizures or papilloedema. Magnetic resonance imaging with magnetic resonance venography is the investigation of choice. Anticoagulation with heparin remains the mainstay of treatment, even in the presence of intracerebral haemorrhage.

Abstract
A rare manifestation of systemic lupus erythematosus (SLE) is cerebral venous sinus thrombosis (CVST), in which early diagnosis and aggressive therapy are of prime importance for favorable outcome. The pathogenesis of CVST is largely unknown, but it is thought to be caused by cerebral vasculitis, antiphospholipid antibodies or other conditions associated with enhanced coagulability. We describe two cases of SLE with CVST which were not associated with antiphospholipid antibodies. Both cases were treated with immunosuppressants (intravenous methylprednisolone and cyclophosphamide pulse therapy) and anticoagulant drugs (heparin and subsequent maintenance therapy with warfarin). There was a marked improvement of neurologic symptoms with the disappearance of thrombus in a follow-up MRI. The possibility of CVST should be considered in any patients with SLE who show neuropsychiatric manifestations.

Abstract
Although intravenous (i.v.) heparin is widely used as the first line treatment for cerebral venous and sinus thrombosis (CVST), the most appropriate therapy for this disease is still controversial. We report 2 cases of CVST who were successfully treated by means of loco-regional thrombolysis with urokinase. In the first case we chose this treatment instead of i.v. heparin because clinical conditions of the patient appeared critical for life on hospital admission; in the second case loco-regional thrombolysis was performed because a full-dose heparin treatment over 8 days failed to improve the clinical picture of the patient. In the literature, there are no established criteria for the use of loco-regional thrombolysis in CVST. On the basis of our own experience and few previous reports on the matter, we suggest that loco-regional thrombolysis should be considered an appropriate treatment for CVST when patients are at life risk, when an involvement of deep cerebral veins is present or when, after full heparinization, patients are doing poorly clinically.

Abstract
A 47-year-old male receiving anticoagulant therapy for thrombophlebitis in the left leg for several years presented with mild left hemiparesis and ipsilateral hypesthesia. The cause of the thrombophlebitis was still unknown. Magnetic resonance (MR) imaging showed subacute thrombosis of both the superior sagittal sinus (SSS) and a cortical vein in the right cerebral hemisphere. Fluid attenuation inversion recovery axial MR imaging demonstrated these lesions more obviously than conventional T2-weighted axial MR imaging. Right carotid angiography showed a partial SSS filling defect and occlusion of the cortical vein with collateral circulation. Coagulation studies revealed decreases in both protein C activity and antigen levels with normal levels of blood coagulation factors II, VII, IX, and X and protein S activity and antigen. The patient's mother had normal levels of both protein C activity and antigen, but his father had decreased levels. The diagnosis was SSS and cerebral cortical venous thrombosis caused by congenital protein C deficiency. The patient was treated conservatively, and his clinical course was uneventful. His neurological dysfunctions recovered within approximately 3 weeks after the onset. Ten months later, right carotid angiography showed recanalization of the SSS and partial filling of the cortical vein. Anticoagulant therapy has been continued, and no cerebral venous thrombosis has recurred during the 1.5 years after the onset.

Abstract
Acute headache may be the presenting symptom of several conditions. Sometimes, a headache with an abrupt onset and unusual severity may occur, experienced by the patient as the worst headache ever. The diagnostic evaluation primarily aims at ruling out subarachnoid haemorrhage (SAH), as well as other serious causes of acute headache, such as meningitis or stroke. The clinical examination should immediately be followed by cerebral computed tomography (CT). A CT scan will reveal 95% of SAHs, provided that it is performed within the first 24 hours after headache onset. If the CT scan is normal, a lumbar puncture should follow, preferably 12 hours after the onset of headache, unless infectious meningitis is suspected. If infectious meningitis is strongly suspected, lumbar puncture should be performed without delay. The spinal fluid should be investigated by spectrophotometry, in order to obtain optimal diagnostic accuracy for SAH. This article briefly reviews the various conditions that may present with an acute headache.

Abstract
The case of a patient with partial superior sagittal sinus and partial right sided transverse sinus thrombosis, and posterior fossa venous collaterals is presented. We report on the use of venous transcranial colour-coded duplex sonography (TCCS), combined with a new three-dimensional transcranial duplex data acquisition system, which allows free hand scanning of the region of interest. TCCS with three-dimensional image reconstruction allowed a more precise spatial localization of venous flow signals in the posterior fossa and facilitated the understanding of the haemodynamics of the venous collateral network.

Abstract
We describe 3 patients who developed infectious aneurysms of the cavernous carotid artery. The aneurysms were due to sphenoidal sinusitis in two patients and due to endocarditis in one. The acute and septic onset of the cavernous sinus syndrome, suggested thrombophlebitis of the cavernous sinus in all 3 patients. The diagnosis was established by magnetic resonance imaging and magnetic resonance angiography. Therapeutic internal carotid artery occlusion was indicated for a fissuration of their aneurysm manifested (n=3) by an episode of epistaxis (n=2) and blood in sphenoid sinus (depicted by MRI) in one case. We discuss the pathophysiology and management of bacterial aneurysms of the cavernous carotid artery. Close clinical and imaging follow-up should be performed for patients under antibiotherapy. Selective angiography with therapeutic occlusion of the carotid artery is discussed in patients with persistence of symptoms or if clinical findings are suggestive of fissuration or if aneurysmal sac diameter increases on follow-up imaging studies.

Abstract
BACKGROUND AND PURPOSE Cerebral venous thrombosis is a rare entity that can be difficult to manage. Intrasinus thrombolysis is an increasingly applied intervention, but this modality carries an increased risk of hemorrhage. We describe for the first time an option with a potentially lower incidence of intracranial bleeding, the combination of the AngioJet rheolytic thrombectomy catheter with intra-arterial thrombolysis, in 2 patients with extensive dural sinus thromboses, preexisting intracranial hemorrhage, and severe progressive neurological deficits despite heparin therapy. METHODS Four procedures were performed in 2 patients with thromboses in the superior sagittal and transverse sinuses (right in 1 patient and bilateral in 1 patient) and cortical veins. Rheolytic thrombectomy was performed in the sigmoid, transverse, straight, and superior sagittal sinuses; this technique involves the use of the Bernoulli effect to create a vacuum that fragments and aspirates thrombus. For associated persistent cortical vein thromboses, low-dose intra-arterial thrombolysis was used. RESULTS Both patients had excellent angiographic results with sinus reopening after rheolytic thrombectomy and cortical vein reopening after intra-arterial thrombolysis. Follow-up CT showed no change in 1 patient and increased preexisting intracranial hemorrhage in the other. One patient had a negative hypercoagulable workup, and the other patient had probable anti-phospholipid antibody syndrome. At 6 months, both patients had excellent clinical outcome with no neurological deficits except mild short-term memory loss in 1 patient. CONCLUSIONS The combination of rheolytic thrombectomy with intra-arterial thrombolysis is a treatment modality that allows accelerated recanalization of occluded dural sinuses and cerebral veins with lower doses of thrombolytic agents.

Abstract
Posttraumatic dural sinus thrombosis (DST) in children has rarely been described in the literature. Over a period of two years (1994-1996) we treated 131 children (n=131) with minor or severe head injury requiring a cranial computed tomography (CT) scan. DST was found in eight patients (6.1%), five with mild and three with severe cranial trauma. Diagnosis was suspected either because of a skull fracture crossing over a dural sinus or because of a hyperdensity at a dural sinus in the noncontrast CT scan. Enhanced CT scan was used to confirm DST. No specific symptoms related to DST were observed. DST was managed conservatively in all patients and recovery was uneventful. Recanalization of the sinus was documented to occur within three weeks to six months in six children. One patient showed a residual clot after five months and another did not have a follow-up CT scan. Based on our data we conclude that neither surgical nor medical intervention is indicated in traumatic DST in children.

Abstract
OBJECTIVE AND IMPORTANCE The frequent association of dural arteriovenous fistulae (DAVFs) and dural sinus thrombosis may render the treatment of these complex lesions difficult. We report a case of DAVF eradicated by recanalization of the chronically thrombosed transverse sinus (TS) and sigmoid sinus followed by balloon angioplasty and stent deployment at the site of the fistula. CLINICAL PRESENTATION A 52-year-old man presented with a Type IV DAVF of the left TS with widespread white matter changes secondary to venous hypertension. Arterial feeders arose from the left internal carotid, external carotid, and vertebral arteries. The distal segment of the left TS, the left sigmoid sinus, and the proximal segment of the right TS were occluded. Reverse flow was observed in the deep venous system and in the superior sagittal sinus. INTERVENTION Endovascular access was gained through the left internal jugular vein. Mechanical recanalization of the thrombosed left TS and sigmoid sinus was followed by balloon angioplasty and placement of six overlapping stents extending from the TS to the proximal internal jugular vein. Angiograms performed after surgery showed resaturation of antegrade venous drainage as well as complete eradication of the fistulous connections. The patient was discharged with an improving clinical CONCLUSION Recanalization of a chronically occluded dural venous sinus through a jugular approach is feasible. In addition to eradicating cerebral venous hypertension by reestablishing antegrade venous drainage, balloon angioplasty and stent deployment at the DAVF site produced complete closure of the fistula. This may prove to be a new therapeutic strategy for management of DAVF.
